文献[1]介绍了科塞尔从单纯静电理论出发,通过定量计算配合能来解释配合物可能的配位数问题。这种处理方法简明易算,所得结论与事实相符也较好,故有一定参考价值。科塞尔从“离子是不可压缩的球体,且各有关正、负离子的半径都相等”的假定开始其定量计算。笔者认为,有可能对此假定作一些改进,以增加其结论的可信性。事实上,既然只考虑单纯的静电作用,则中心离子M~(2-)可抽象为一个+Z电荷的质点, The literature [1] introduced Kozel starting from the simple electrostatic theory, through the quantitative calculation of the binding energy to explain the possible complex coordination number problem. This method is simple and easy to calculate, the conclusion is consistent with the fact that the facts are good, so there is a certain reference value. Kozel begins his quantitative calculation from the assumption that “the ion is an incompressible sphere, and each of the positive and negative ions has the same radius”. The author believes that it is possible to make some improvements to this assumption in order to increase the credibility of its conclusion. In fact, since only the pure electrostatic effect is considered, the central ion M ~ (2-) can be abstracted as a + Z charged particle,
